Possible Causes

How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the control panel or display housing.

  • Access the display panel: Remove the front control panel screws or clips to expose the user interface board and ribbon cable.
  • Inspect the ribbon cable: Look for kinks, cuts, or burn marks. Reseat both ends of the cable firmly into their connectors.
  • Clean connectors: Use electronic contact cleaner and a soft brush to clean any oxidation from connector pins.
  • Check for moisture: Ensure there is no condensation or water intrusion around the display area. Dry thoroughly if present and address any gasket issues.
  • Test operation: Reassemble, restore power, and see if E14 clears and buttons respond normally.
  • Replace the user interface board if the error persists and the main board appears functional. If a new UI does not resolve the issue, the main control board may need replacement.
